All ISO standards are now set out in identical fashion, following a framework called Annex SL. As a result of this there is now much more commonality among the main ISO standards:
• ISO 9001 – Quality Management
• ISO 14001 – Environmental Management
• ISO 27001 – Information Security Management
• ISO 45001 – Occupational Health and Safety
All of these standards have the same layout and format, and there is a considerable amount of duplication between these standards. The consequence of this is that it is increasingly straightforward to combine two or more standards into an Integrated Management System (IMS).
